Pest control: The Black Powder solution

    A reader sent this in to TFB when they stumbled across an odd patent for a type of “Vermin Control”, patented in 1882 by a certain James A Williams. It uses a lever that a rodent would feasibly step on and would be connected to a trigger, which would set it off. It specifically says the patent may also be used against burglars…

    A represents a suitable board, from which rises the three standards B, upon which the revolver or pistol U is supported in position. Pivoted to the middle standard is the lever 1), and fastened in any suitable manner to the front end of this lever is the rod G, which extends backward and bears against the trigger of the fire-arm. Bearing upon the rear end of the lever D is a suitable spring, H, which will throw the front end of the lever D upward as soon as the lever is left free to move, and in throwing up the front end of the lever D the rod connected thereto is forced backward, so as to push back the trigger. Secured to the front end of the boardA is a suitable spring actuated treadle, I, the rear end of which forms a trigger to catch over the front end of the lever D. This treadle is first made to catch over the front end of the lever D, which sets the trap, and then the treadle is forced into-the animals hole or burrow. The animal, in corning out, steps upon the treadle and presses the treadle down, which releases the lever, when the spring immediately causes the lever to fly upward and the rod then forces back the trigger and causes the fire-arm to go off, killing the animal that is in front of it.

    This invention may also be used in connection with a door or window, so as to kill any person or thing opening the door or window to which it is attached.

    I am aware that burglar-alarms of various kinds have been used, and which have been connected to windows and doors in such a manner that the opening of the window or door causes a pressure upon a lever which discharges a tire-arm; but in no case have the parts been arranged and combined as here shown and described.
